Abstract

The invention relates to a continuous casting equipment for a flow of liquid steel from a tundish (2) into an ingot mould (1) through a hollow jet nozzle or HJN nozzle, comprising a deflector or dome (6) for diverting the incoming metal towards the side walls of the nozzle, said nozzle further including means for injecting a metallic powder or a finely ground solid metallic material (13, 13A, 14) under said dome (6) in an injection area (15), and means for injecting a non-oxidant gas (16, 17) for creating and maintaining the hollow jet, characterised in that the powder injection means (13, 13A, 14) are independent and physically separated from the non-oxidant gas injection means (16, 17) so that during the operation, the non-oxidant gas is not used as a vector for powder injection.
